|
|
*
|
|
*
|
|
* Based on (at least) the following plug-ins:
|
|
* Screenshot
|
|
* GIF
|
|
* Randomize
|
|
*
|
|
* Any suggestions, bug-reports or patches are welcome.
|
|
*
|
|
* This plug-in interfaces to the TWAIN support library in order
|
|
* to capture images from TWAIN devices directly into PIKA images.
|
|
* The plug-in is capable of acquiring the following type of
|
|
* images:
|
|
* - B/W (1 bit images translated to grayscale B/W)
|
|
* - Grayscale up to 16 bits per pixel
|
|
* - RGB up to 16 bits per sample (24, 30, 36, etc.)
|
|
* - Paletted images (both Gray and RGB)
|
|
*
|
|
* Prerequisites:
|
|
* Should compile and run on both Win32 and Mac OS X 10.3 (possibly
|
|
* also on 10.2).
|
|
*
|
|
* Known problems:
|
|
* - Multiple image transfers will hang the plug-in. The current
|
|
* configuration compiles with a maximum of single image transfers.
|
|
* - On Mac OS X, canceling doesn't always close things out fully.
|
|
* - Epson TWAIN driver on Mac OS X crashes the plugin when scanning.
